Explanation
Edge locations in services like Amazon CloudFront and AWS Global Accelerator provide significant benefits for globally distributed applications, including reduced latency, enhanced security, and improved global availability. These features are especially useful for businesses that need to deliver content quickly and securely to users worldwide.
- A. Correct.
Reduced latency is a key benefit of edge locations as they cache content closer to users, minimizing the time it takes for data to travel across the internet.
- B. Correct.
Edge locations enhance security by integrating features like AWS Shield for DDoS protection and encryption mechanisms.
- C. Incorrect.
While edge locations allow for some compute functionality through services like AWS Lambda@Edge, running serverless applications is not a primary benefit related to caching or global acceleration.
